I'm finding that if I eat the wrong things, or at the wrong time of day, I can end up with blinding migraine headaches. I used to never get migraines. Cluster headaches, yes, but not migraines.
Last year, things started to change.
Now if I eat chocolate early in the day, or too much sugar before eating protein, I will pay a high price for it - and not just at the waistline!
It's so much easier to just have good nutrition than to deal with the headaches. Literally!
